iOS 9 dark keyboard bug

Why does the iOS keyboard have blank, black keys sometimes?

Update! This issue appears to be fixed in iOS 10. Hooray!

dark keyboard problem

This is an iOS 9 bug that affects the dark system keyboard. Some of the keys appear blank after a full-screen pop-over (like Touch ID) is dismissed.

We have already reported this issue to Apple and are hopeful that it will be addressed in a future update.

For the time being you can restore the normal keyboard appearance by switching to any other keyboard (e.g. emoji) and then back again.
